'MACHINE FOR SROLLING AXLES.

SPECIFICATION formingpart of Letters Patent No. 241,106, dated May 3, 1881.

Application tiled April 2-2, 1880. (No model.)

To all whom it may concern Be it known that I, JOHN HENRY WHITNEY, of the city, county, and State of New York, have invented an improved Machine for Roll ing Axles, of which the following is aspecili-. cation.

The object of my invention is to provide anew and improved machine for rolling axles, rivets, bolts, and other articles in a simple and effective manner.

The metal is fed into the machine through a suitable guide consisting of a loose flanged short tube held 'between two or more rollers or adjustable slides, the metal being held between the rollers bya pairof automatic tongs, which close as the work progresses.

In the accompanying drawings, Figure l is a front elevation of my improved rolling-machine, showing the same arranged for rolling axles. Fig. 2 is a front elevation of the same, showing it modified and arranged for rolling buttoirliead rivets. Fig. 3 is an end elevation of the same. Fig. 4 isa cross-sectional elevation on the line a m, Fig. 2, showing the arrangement of the cam-wheel. Fig. 5 is a side elevation of the apparatus for guiding the metal into the machine. Fi 6 is a plan view and end elevation of the same. Fi 7 is a cross-sectional elevation of a modification of the apparatus for guiding the metal into the machine. Fig. 8 is a front elevation of'the same. Fig. 9 is an end and side elevation of the tongs for holding the work between the rollers. Fig. 10 shows the rollers as modified for rolling rivets with truncated cone-heads.

Similar letters of reference indicate corresponding parts.

The shafts A and B are journaled in the frame 0, and have spur-wheels D D mounted on one end, and rollers E E of some suitable shape mounted on the other end. The spurwheels D D engage with a pinion, F,n10unted on a shaft, Gr, provided with a fiy-wheel, H, a fixed pulley, 1, and a loose pulley, I. The

5 journal J of the outer end of the upper shaft rounded by a sleeve, K, upon the outer end of which a geared wheel, L, (engaging with a pinion, M, on the shaft 13,) is mounted, and a cam-wheel. N, resting upon a smooth wheel, 0, on the shat'tB, is mounted on the said sleeve K. The wheel L and pinion M may be replaced by a worn'l-wheel, L, and a worm, M, especially when a very slow movement, which is independent of the movement of the shafts A and B, is desired.

' The rollers E E, which are used to roll avles, are beveled according to the bevel that the spindie of the axle is to have, and are provided with grooves a a. near the outer ends, which grooves form the collar between the axle and the spindle.

Ifrivets are to be rolled, the rollers E IE will be composed of a series of disks, b l), which are mounted on the shafts, and are held by an end plate,'c, which has the shape of the head of the rivet. lf rivets with truncated cone heads are desired, knives P 1? must be attached to both ends of one or both rollers E E for the purpose of cutting off the metal. The rollers are pressed against each other by a strong spiral or other spring,-Q,the tension of which can be regulated by means of a screw operated by a hand-wheel, It. The metal is fed into the machine through a guide placed in front of the ends of the rollers, and consisting of a flanged tube, S, mounted between three or four rollers, T T, on a suitable frame, cl,- or the tube S can be loosely held by two or more L- shaped slides, U, which can be adjusted according to the diameter of the tube S, and are held, when adjusted, by means of screws 0 e passing through the slots f f in the slides U,.

and entering the frame or standard g. The tube is mounted between the rollers so as to permit it to be rotated freely with the bar passing through it. The sliding plates are adjustable to suit the diameter of the tube, which must have aperforat-ion corresponding to the diameter of the rod that is to be introduced between the rollers. The work is held between the rollers E by a pair of tongs formed of two L-shaped levers, V, pivoted below the shaft A in such a manner that the shanks hot the said levers embrace the said shaft A. The inner sides of the shanks h are rounded and then beveled, so that they are square when the shaft A descends. The lower ends of the levers Vare drawn apart by spiral or other suitable springs,

too

W \V. The tubes S are varied in size, according to the size of the worln The operation is as follows As the pinion F is between the two wheels 1) D, it is evident that they will both rotate in the same direction, and as the pinion M is much smaller than the spur-wheel L it is evident that the sleeve K will not rotate as rapidly as the shaft A. If the shaft G is rotated from left to right, the shafts A and B and the rollers E E will both be rotated from right to left, and the cam-wheel N will be rotated from left to right. If the cam proper, m, only of the cam-wheel N rests on the smooth wheel 0, the rollers E E will be atthe maximum of separation, and the hot iron is now passed through the guide-tube S into the space between the rollers. As the camwheel N continues to rotate, the rollers come nearer to each other, and the pressure of the spring Q upon the rollers causes a spreading of the iron 5 but as the rollers rotate much more rapidly than the cam-wheel N, the result is that the rivet or axle is being formed as rapidly as the iron spreads. It the cam-wheel N is in the position shown in Fig. 4, the rollers are as close to each other as they possibly can be, and the next moment they will begin to separate very rapidly, permitting the end of the iron rod Xto be pushed in between them again. If the object can only be formed with great difliculty, the worm M and the wormwheel L should preferably be used, as with them the speed of the sleeve K can be reduced as much as may be desired or necessary. As the cam-wheel N raises the roller E of the shaft A at every revolution, it is necessary that the journal J be pivoted. If the shaft A is raised the lower ends of the levers V are drawn apart by the springs \V \V, causing the upper shanks,

h h, to lie up closely against the shaft A; but as the shaft A gradually descends it spreads the shanks h, and the lower ends of the levers V are brought together, holding the work between them. The work gets thinner as the shaft A descends, and at the same time the lower ends ofthe levers V are pressed closer together. As soon as the shaft A rises the lower ends of the levers Va-re drawn apart again by the springs W.

In the above-described manner axles, rivets, bolts, or any other similar articles can be rolled rapidly and in first-class quality. For making axles two machines may be preferably used at the same time, each rolling one end of the axle.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- The combination, with the shafts A and B, of the sleeve K, the cog-wheel L, pinion M, cam-wheel N, and smooth wheel 0, substantially as herein shown and described, and for the purpose set forth.

2. The roller-shaft B, pinion M, and smooth Wheel 0, in combination with the pivoted hearing J, sleeve K, wheel L, cam N, roller-shaft A, screw and hand wheel R, and spring Q, as and for the purpose specified.

3. The combination, with the shaft A, provided with a pivoted journal, J, of the L- shaped levers V, pivoted to the frame at the sides of the shaft A, substantially as herein shown and described, and for thepurposes set forth.

JOHN II. WHITNEY.
